BACKGROUND

The present disclosure relates to the field of information processing technique, and more particularly, to an information processing method and an electronic device.

In a Long Term Evolution-Advanced (LTE-A) mobile communication system, Small Cell is introduced in order to enhance the capacity of network users in a hot spot, increase the flexibility of network deployment, and meanwhile improve the spectral utilization. Small Cell is quite different from the previous concepts of Home eNB and Pico Cell: based on whether a Small Cell can be independent of a Macro Cell, the Small Cell can be divided into Standalone Small Cell and Non-standalone Small Cell, the Standalone Small Cell refers to that operation of the Small Cell can be completely independent of a Macro Base Station, it is mainly to solve a coverage problem; whereas the Non-standalone Small Cell refers to operation of the Small Cell must rely on a Macro Base Station, needs the Macro Base Station to schedule, it is mainly to share the Macro Base Station's load. The Macro Base Station and the Small Cell adopt different frequency bands or the same frequency band. For example, the Small Cell usually adopts a frequency band of 3.5 GHz. Due to the small coverage of the Small Cell, deployment of the Small Cell is not as strict as that of a Macro Cell. After the Small Cell is completely turned on, co-frequency interference between the Small Cells or between the Macro Cell and the Small Cell are very serious. Related measures are required to avoid such interference. However, currently, there are no related techniques available for reference.

Hereinafter, substance of the technical solutions of the embodiments of the present disclosure will be further explained through specific examples.

The embodiments of the present disclosure are applicable to the Non-standalone Small Cell controlled by a Base Station. After the Non-standalone Small Cell is deployed, Discovery RS (DRS) is introduced, the cycle of each DRS is 40 ms, its emergence position is distributed by a Macro Base Station in different 1 ms sub-frames based on a different Small Cell, the signal transmitted by the Small Cell may be divided into three states as follows:

On-state: like a Macro Cell, transmitting conventional reference signals such as PSS, SSS, CRS and physical channels such as PBCH, PDCCH, and PDSCH; a protocol layer monitors a control command transmitted by the Macro Base Station through X2-C.

Off-state: the Small Cell does not transmit any signal under this state, meanwhile a protocol layer monitors a control command transmitted by the Macro Base Station through X2-C.

Dormant-state: the Small Cell only transmits the DRS signal periodically under this state, without transmitting any conventional reference signal, meanwhile a protocol layer monitors a control command transmitted by the Macro Base Station through X2-C.

A state shift of the Small Cell is controlled completely by the Macro Base Station, after the UC ends the RRC connection, it cannot reside in the Non-standalone Small Cell.

When the Macro Base Station detects and finds out that the capability of the connected UE supports carrier aggregation, dual-link, or the load of the Macro Base Station enters a cardoon, then the Macro Base Station turns on the Non-standalone Cell by the following steps.

1. The Macro Base Station controls the UE Small Cell that may be covered by multiple subordinate signals to enter a Dormant state (if the Small Cell is in an On state, then it remains unchanged), meanwhile specifying the transmission power of the Small Cell, if is an already-turned-on Small Cell, its transmission power remains unchanged.

2. The Macro Base Station transmits, through an RRC message, a serial number that specifies the Discovery RS signal of a sub-frame and a sub-frame position of the signal to the UE, and notifies the UE to asynchronously measure the Discovery RS signal, after the UE completes the measurement, it reports the measured RSRP to the Macro Base Station; meanwhile, the Macro Base Station notifies a relevant Small Cell to perform a co-frequency interference measurement, and reports the measurement result to the Macro Base Station.

3. The Macro Base Station selects, based on RSRP measured by the UE on the Discovery RS and the result of co-frequency interference measurement between Small Cells, several suitable Small Cells, standards for the selection are:

the signal strength of receiving Discovery RS (RSRP) measured by the UE is larger than −110 dBm and the strength of co-frequency interference measured by the Small Cell is less than −150 dBm; a Small Cell that satisfies the aforesaid condition is called a suitable Small Cell.

4. If there is no Small Cell that satisfies the aforesaid condition, the transmission power of the Small Cell that is in a dormant state is changed (i.e., increasing the transmission power), until a suitable Small Cell is selected; in this way, the transmission power of all candidate Small Cells is specified, and will not change after being turned on.

5. The Macro Base Station turns on the Small Cell that is in a dormant state and is a suitable Small Cell, and turns off the non-suitable Small Cell that is not selected, thus the first stage of DRS signal measurement is completed.

6. The Macro Base Station notifies the UE to measure the RSRP of the

Cell-specific RS of the Small Cell that is turned on, and reports the measurement report to the Macro Base Station; the Macro Base Station selects one best Small Cell based on the following rule:

rule for the best Small Cell: the RSRP of the Cell-specific RS of the Small Cell that is turned on is the largest.

7. Turning off the Small Cell that is not selected and switches from the dormant state to the On state during the first stage, only one best Small Cell is retained.

8. According to specific cases of the user: comprising the Macro Base Station and the Small Cell will form a carrier aggregation, or form a dual direction, or the Macro Base Station will switch to the Small Cell. The specific protocol process is exactly the same as that from a Macro Cell to a Macro Cell.

9. After the UE ends the RRC connection, it cannot reside in the Small Cell, but must return and reside in the Macro Base Station. When all the UEs in the Small Cell end the RRC connection, the Macro Base Station turns off the Small Cell.

As shown in FIG. 8, the UE and the Macro Base Station form a normal RRC connection, when the Macro Base Station finds out that its load enters a cordon, it needs to move the UE in a Small Cell, the Macro Base Station judges, based on the physical position of the UE, Small Cells 3, 4, 5 may become a suitable Small Cell for the UE, Small Cells 3, 4, 5 all are in an Off state, Small Cell 1 is in an On state because of being connected by the other UE. A first stage of selection of a group of suitable Small Cell: Small Cells 3, 4, 5 enter a dormant state under the instruction of the Macro Base Station and transmit the Discovery RS signal, the UE measures the Discovery RS signal of Small Cells 3, 4, 5, meanwhile Small Cell 3, 4, 5 measure the co-frequency interference which it is subjected to. The result is: the signal strength (RSRP) received by the UE is: Small Cell 3>Small Cell 4>Small Cell 5, but none of them exceeds −110 dBm, but since Small Cell 3 gets co-frequency interference from Small Cell 1, and the interference strength exceeds −150 dBm, Small Cell 3 is excluded from being a suitable Small Cell, and therefore is turned off. In this way, Small Cells 4, 5 become a group of suitable Small Cell. A second stage of selection of the best Small Cell: the Macro Base Station turns on Small Cells 4 and 5 completely, the UE measures the Cell-specific RS signal of Small Cells 4 and 5, to obtain the most reliable reception signal strength, with a result as below: Small Cell 4>Small Cell 5. Finally, Small Cell 4 is selected as the best Small Cell, Small Cell 5 is turned off. The UE is switched to Small Cell 4, which reduces the load of the Macro Base Station.
